COUPLlG `DEVICE FOR SAFE-SPINDLS.

SPECIFICATION forming part of Letters Patent No. 269,953, dated January 2, 18.83.

l Application filed September 2, 1882. (No model.)

To all whom t may concern Beit known .that I, LnoPoLnT MoRiTz, a citizen of the `United States, residing at New. port, in the county ot' Campbell and Stateot' Kentucky, have invented certain new and useful Improvements in Bank-Safes, of which the following is a specitication.

My invention consists in applying a pecu Marly-constructed couplingdevice to the inner 1o end of a bank-safe spindle, said device being so arranged as to allow the spindle to beturned uninterruptedly either to the right or left when the `main bolt and the train-bolts are shot, and without aecting any ot' the locking mechan- 1 5 ism, while the retraction of the main boltcauses the coupling device to engage with said spindie, in order that the train-bolts may be withdrawn from their sockets in the safe-door frame. l

The coupling device consists essentially of, a hub mounted on but not attached to the spindle, and having a suitable connection with the train-bolts, said hub being recessed to receive a slide provided with a slot terminating with an enlargement or eye. Furthermore, this slide is notched near one end to receive a dog projecting from the main bolt, in order that the retraction of this bolt may cause the slot of the slide to engage with a square 7 ofthe 3o spindle, andthereby temporarily lock the latter to the hub and allow the train-bolts to be withdrawn, as hereinafter more fully described, and pointed out in the claims.

In the annexed drawings, Figure lis an elevation of the inner side of a safe-door provided with -lny improvements, the bolts'beng shown protruded. Fig. 2 is an enlarged elevation ot the coupling device in the saine poy sition as seen in the precedingillustration, the 4.0 stump that communicates motion to the trainbolts being in section. Fig. 3 is a similar elevation, but showing themain bolt retracted andthe slide engaged with the square ot' the spindle. Fig. 4 is an 'elevation showing the now coupled spindle, hub, and slide turned so as to unlock the train-bolts. Figo' is a vertical section ot' the device, the various members of the same being inthe same position as seen in Figsml and 2, and the central portion of the 5o spindle beingomitted. Fig. Gisavertical section of the various members of the coupling device detached from each other. In the above views the Washer is omitted from Figs. 2, 3, i and 4. y.

Referring to Fig. 5, A and B represent, respectively, the outer and inner plates of a safedoor of any desired thickness, said 'door being traversed by a customary spindle, C, having an external lever-handle, c. The extreme inner end ot this spindle is threaded at d to re- 6o i ccive a nut, D, wherewith the coupling device is secured in position on said spindle. The principal member ot' this couplingis a hub, E, provided with an axial bore, e, adapted to turn freely on spindle C, said hub being further provided with-a projecting lug, F, slotted atf to receive a stump, G, that communicates motion to the train-bolt mechanism. In Fig. l thisstump is shown as attached to a lateral projection, 7L, of the tie-bar H, that connects the 7o train-bolts I I', saidrprojection being represented as located between the lug F and plate B; but in Fig. 5 the stump G is shown pro j'ecting from the tie-bar H, thereby indicating that saidstump may be connected either directly orindirectly to thebolt-shiftingmechanism. The inner face of hub E is recessed at J to receive the vreciprocatin g slide K, the latter being provided with a longitudinal slot,

k, terminating at one end with .an eye or en- 8o largement, L. This slot is ot' such a width as to receive the square N ot' spindle C, while the diameter ofthe eye L is alittle greater than that of the spindle in order that the latter may turn ireely therein. Furthermore, the slide is notchedat O to receive a hook-shaped dog, P, projecting from the main boltR ot' the combination or other bank-lock S.

T is a washer that retains the slide K k L within the recess J, said washer havinga non- 9o circular eye,.t, that its over the shorter portion U ot' the square ot' spindle G.

Visa fixed collar on spindle O for the hub E to bear against. i

X isa socket that supports the protruded end of slide K, which socket may be made in the bolt-barb when practicable; or said socket may be secured to theplate B of the safe-door. When the train-bolts I l are thrown, as seen in Fig. 1`,and` the main boltlt is shot from lock roo S, the slide K isfadvanced so far as to bring,

its eye L over the spindle C, and as said eye is of somewhat greater diameter than said spindle it is evident the latter can be turned in either direction by the lever c without communicating motion to the hub E. (See Fig. 2.) Consequently said lever can be turned either to the right or left for an indefinite period of time Withouty in the least affecting the position of the train-bolts or otherwise interfering with the locking mechanism of the safe. As soon, however, as the main ,bolt l is retracted, its dog P drags the slide K back a corresponding distance, and thereby engages the slot k withthe square N ot' the spindle, as seen in Fig.3. Evidently/the hub, slide, and spindle are now temporarily locked or coupled together, and by simply turning lever c in the proper direction to retract the train-bolts I l', the free end of slide K swings down and disengages its notch O from the dog P, as seen in Fig. 4. When the safe is tobe locked the handle c is turned, so as to force the train-bolts I I into their appropriate sockets,whieh turning of said handle restores slide K to its normal position and 4causes the dog P to engagewith notch 0. As

soon as the main bolt4 R is shot the slide is again advanced, so as to bring its eye N over the spindle C. thereby disconnecting all of the coupling devices 'and allowing the spindle C to be turned Without'aecting any of thelocking mechanism of the safe..

.The above is a description of the preferred form ot' my coupling device; but it is evident the details of the same may be considerably vsuitable attachment thereto.

effected by :turning the latter up instead 'of down; but as this arrangement would necessitate the swinging of lever c in the wrong direction, such an alteration is discouraged.`

Again, the tie-plate El may be connected to lug F with a link, or the upper end of said lug may take the shapeof asegmental gear adapted to engage with a rack on the under side ot' the` lateral extension h of said plate, or-of any Finally, the upper and lower sides of recess J may be undercut, and theedges of slide K be beveled so as to dovetail therein, by which arrangement the4 screw d, nut D, square U, and washer T t would be dispensed with. I claim as my invention- The combination of squared spindle C N, recessed hub E e J, lng F, slotted and notched slide K 7c L O, main bolt R, and dog P, said lug F'being adapted to communicate motion to the traiuLbolts, substantially as herein de' scribed. a

In testimony whereofI affix my signatnrein presence of two Witnesses.
